Your Jyotish birth chart on the sidereal zodiac: the Rasi and Navamsa charts, your birth star, your planetary periods (dashas), the Panchang of your birth, the Manglik check and Sade Sati.
Sidereal zodiac with the Lahiri (Chitrapaksha) ayanamsa, the Indian national standard, defined as Swiss Ephemeris does and checked against it to within a third of an arcsecond; planet positions within a third of an arcminute. Planets from Astronomy Engine. Rahu and Ketu: mean nodes. Houses: whole signs from the Lagna. Navamsa (D9): each sign split into nine parts of 3°20′. Vimshottari dashas from the Moon’s nakshatra, with a year of 365.25 days; other software may use a slightly different year, which moves dates by days. Panchang: tithi from the Moon’s angle ahead of the Sun, yoga from their sum, and the weekday counted from sunrise, as in Vedic practice. Manglik: Mars in the 1st, 2nd, 4th, 7th, 8th or 12th house from the Lagna or the Moon; traditions differ on this check and on its cancellations. Sade Sati: sidereal Saturn in the sign before, on and after the Moon sign. Everything is calculated in your browser; nothing is sent anywhere.
